[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Does anyone know where I can source a copy of a booklet called 'Square Composition' which was written by a Hasselblad employee? I have a shiny new 503CW and I have been told that the booklet is a good reference for the composition of 6x6 pictures. Please reply to my private mail and then I won't annoy everyone on the list. Thanks.
